。 In a pilot relay that supplies nozzle back pressure as input pressure, amplifies it, and outputs it as output pressure, an annular groove that communicates with the bleed hole is formed in the center of the outer peripheral surface of the housing, and both ends of this annular groove are It is formed shallower than the central part to form a cover supporting step, and is formed in a ring shape with both end surfaces open, and a part of the circumferential surface is cut open over the entire length in the axial direction, and this notch One of the open ends is bent outward and overlapped with the outer periphery of the other notched open end while maintaining a required gap, thereby forming a drainage and exhaust port between these notched open ends. A pilot relay characterized in that the drain/exhaust port is removably and rotatably fitted into the cover supporting stepped portion of the annular groove with the drainage/exhaust port facing downward.
